In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Note that, the product lifted by the hook in the following embodiment is the battery module 400, but the product lifted by the hook may be a fixture, a mold, or the like, in addition to the battery module 400. In fig. 1 and 2, the specific structure of the battery module 400 is simplified in order to mainly show the structure of the hooks, and only a portion of one end plate of the battery module 400 is shown in fig. 1 and 2.

Referring to fig. 1 to 4, a hook according to an embodiment of the first aspect of the present application is used to hoist a battery module 400, the battery module 400 is provided with a supporting portion 421 (refer to fig. 4), and the hook includes a hoist 100 and a limit seat 200. One end (for example, the lower end) of the hanging member 100 is provided with a first supporting portion 110. When the hanging member 100 is at the first position (refer to fig. 4) with respect to the battery module 400, the first supporting part 110 supports the abutting part 421. When the hanging member 100 moves along the first direction relative to the battery module 400, the overlapping area of the projections of the first supporting portion 110 and the abutting portion 421 in the vertical direction is gradually reduced.

The limiting seat 200 is provided with a connecting portion 240, and the connecting portion 240 can be matched with the battery module 400 to limit the movement of the limiting seat 200 relative to the battery module 400 along the first direction.

The limiting seat 200 is further provided with a first limiting portion 220, and the lifting member 100 is further provided with a second limiting portion 120. When the lifting member 100 is located at the first position, the first limiting portion 220 is matched with the second limiting portion 120 to limit the movement of the lifting member 100 relative to the limiting seat 200 along the first direction.

The lifting hook provided by the embodiment of the application has at least the following beneficial effects: when the first limiting portion 220 is matched with the second limiting portion 120, the movement of the lifting member 100 along the first direction relative to the limiting seat 200 is limited, meanwhile, if the connecting portion 240 of the limiting seat 200 is also matched with products such as the battery module 400, the movement of the limiting seat 200 along the first direction relative to the battery module 400 is also limited, that is, the lifting member 100 cannot move along the first direction relative to the battery module 400, the risk that the first supporting portion 110 is separated from the battery module 400 can be effectively reduced.

Specifically, referring to fig. 3 and 4, in order to facilitate the first supporting portion 110 to support the supporting portion 421, the battery module 400 is provided with the relief hole 420 (the relief hole 420 is typically formed on the end plate of the battery module 400), and the supporting portion 421 includes the upper surface of the relief hole 420. When the lifting member 100 needs to lift the battery module 400, only the projection of the upper surface of the first supporting portion 110 and the avoidance hole 420 in the vertical direction at least partially coincides, and then the upper surface of the avoidance hole 420 is supported by the first supporting portion 110 to support the battery module 400 (when the battery module 400 is supported, a plurality of hooks are usually matched together to lift one battery module 400 together).

The plurality of first positions may be provided, so long as the overlapping area of the projections of the first supporting portion 110 and the abutting portion 421 in the vertical direction is not zero, and when the overlapping area of the projections of the first supporting portion 110 and the abutting portion 421 in the vertical direction is maximum, the position of the lifting member 100 is the optimal first position, for example, the first supporting portion 110 in fig. 4 is the optimal position. After the first supporting portion 110 in fig. 4 rotates by 5 °, 10 °, or other angles along the first direction, the position of the lifting member 100 may also be the first position.

Referring to fig. 4, in some embodiments of the present application, the first direction is a circumferential direction (referring to fig. 2, e.g., counterclockwise (looking down from above)).

At this time, the hanging member 100 may support the first supporting portion 110 to the supporting portion 421 or disengage the first supporting portion 110 from the supporting portion 421 only by rotating (for example, rotating about an axis in the up-down direction) relative to the battery module 400 (see fig. 4). The movement mode of the lifting member 100 relative to the battery module 400 is simple, thereby being beneficial to rapidly completing or releasing the lifting of the battery module 400, and the efficiency of lifting the battery module 400 by the lifting hook is high.

Note that the first supporting portion 110 being separated from the abutting portion 421 means that the overlapping area of the projection of the first supporting portion 110 and the abutting portion 421 in the vertical direction is zero, and specifically, refer to fig. 10.

Specifically, referring to fig. 2 and 4, in order to restrain the position of the hanging member 100 with respect to the battery module 400, the battery module 400 is prevented from being separated from the battery module 400 in the forward, backward, leftward and rightward directions of the hanging member 100, resulting in the first supporting portion 110 being separated from the supporting portion 421, and the battery module 400 is provided with a third limiting hole 410, the third limiting hole 410 being communicated with the escape hole 420. When the first supporting portion 110 is to support the supporting portion 421, the lower end of the lifting member 100 is inserted into the third limiting hole 410 until the first supporting portion 110 moves to the vicinity of the avoiding hole 420. By rotating the first supporting portion 110 in a direction opposite to the first direction, the hoist 100 can be moved to the first position, so that the first supporting portion 110 supports the abutting portion 421.

When the lower end of the hanging member 100 is penetrated in the third limiting hole 410, the hanging member 100 is limited by the third inner surface 411 (refer to fig. 4) of the third limiting hole 410, the hanging member 100 cannot be greatly moved in the forward, backward, leftward or rightward directions, the first supporting part 110 is not easily separated from the supporting part 421, and the safety performance of the hook hanging the battery module 400 is higher.

Specifically, to rotate the hoist 100, the first supporting portion 110 can support the supporting portion 421, and the first supporting portion 110 is eccentric with respect to the main body of the hoist 100. When the first supporting portion 110 rotates below the supporting portion 421 with respect to the eccentric portion of the body of the lifting device 100, the first supporting portion 110 can support the supporting portion 421. For example, referring to fig. 2, the cross-sectional shape of the first support portion 110 is substantially rectangular, and the left half of the first support portion 110 is connected to the rod portion of the hoist 100. When the right half of the first supporting portion 110 rotates below the supporting portion 421, the first supporting portion 110 can support the supporting portion 421.

Specifically, referring to fig. 2, in order that the limiting seat 200 has a good constraint on the rotational movement of the hanging member 100 when the connection part 240 of the limiting seat 200 is engaged with the battery module 400, the limiting seat 200 is provided with a fourth limiting hole 210, and the hanging member 100 is inserted into the fourth limiting hole 210, and the hanging member 100 is in clearance engagement with the fourth limiting hole 210. Therefore, when the lifting member 100 rotates along the first direction, the limiting seat 200 can restrict the movement of the lifting member 100.

Referring to fig. 5 and 6, in some embodiments of the present application, the first direction is a straight direction (referring to fig. 5, e.g., a right direction).

Similarly, the hanging member 100 only needs to move in a linear direction (refer to fig. 5, for example, move in a left-right direction) relative to the battery module 400, so that the first supporting portion 110 can support the supporting portion 421, or the first supporting portion 110 can be separated from the supporting portion 421. The movement mode of the hanging member 100 with respect to the battery module 400 is simple, thereby facilitating the rapid completion or release of the hanging of the battery module 400.

Referring to fig. 4 and 7, in a modification of the above embodiment, the cross section of the connection portion 240 is flat-key-shaped. The battery module 400 is provided with a third limiting hole 410, the first direction is perpendicular to the axial direction of the third limiting hole 410, the shape of the third limiting hole 410 is the same as the shape of the cross section of the connecting part 240, and the connecting part 240 is used for being in plug-in fit with the third limiting hole 410.

The first direction is perpendicular to the axial direction of the third limiting hole 410, and no matter the first direction is the circumferential direction or the linear direction, after the connecting part 240 with the cross section being a flat key is in plug-in fit with the third limiting hole 410, the movement of the limiting seat 200 relative to the battery module 400 along the first direction can be limited, so that the restraint is simple and effective. In addition, the plugging engagement of the connection part 240 and the third limiting hole 410 may be rapidly completed, and the movement of the limiting seat 200 relative to the battery module 400 along the first direction may be rapidly achieved, thereby being beneficial to improving the efficiency of connecting and separating the hook from the battery module 400.

The flat key shape refers to a cross-sectional shape of the flat key, and the flat key generally has a double round head type, a flat head type, and a single round head type. The cross section of the flat key with flat head is rectangular, the cross section of the flat key with single round head is a graph formed by replacing one short side of the rectangle with one semicircle, and the cross section of the flat key with double round head is a graph formed by replacing two short sides of the rectangle with two semicircles.

In other embodiments, the cross-section of the connection portion 240 may also be elliptical or polygonal.

The first direction is perpendicular to the axial direction of the third limiting hole 410, and no matter the first direction is the circumferential direction or the linear direction, after the connecting portion 240 with the cross section being elliptical or polygonal is in plug-in fit with the third limiting hole 410, the movement of the limiting seat 200 relative to the battery module 400 along the first direction can be limited, so that the restraint is simple and effective.

In particular, the polygon may be a triangle, a quadrilateral, a pentagon, a hexagon, or other shape.

Referring to fig. 2, in the modification of the above embodiment, the hook further includes an elastic member 310, where the elastic member 310 is connected to the hanging member 100 and the limiting seat 200, respectively, and when the elastic member 310 is deformed, the elastic member 310 can drive the limiting seat 200 to approach the battery module 400, so that the connecting portion 240 is inserted into the third limiting hole 410.

Under the elastic force of the elastic member 310, the limiting seat 200 approaches the battery module 400, thereby facilitating the connection part 240 to be maintained in a state of being inserted into the third limiting hole 410, and the connection part 240 is not easily separated from the third limiting hole 410, thereby facilitating the limiting seat 200 to stably limit the hanging member 100.

Specifically, the elastic member 310 includes a compression spring, and the hook further includes a connection sleeve 320 for installing the compression spring. The compression spring is sleeved on the lifting piece 100, and the lower end of the compression spring is propped against the limiting seat 200. The connecting sleeve 320 is screw-coupled with the upper end of the hanging member 100, and the connecting sleeve 320 is abutted with the upper end of the compression spring. When the connection part 240 is inserted into the third limiting hole 410 and the first supporting part 110 supports the supporting part 421, the compression spring is in a compressed state, the limiting seat 200 has a tendency to approach the battery module 400 under the action of the compression spring, and the connection part 240 is not easily separated from the third limiting hole 410.

In other embodiments, the elastic member 310 may be a rubber sleeve or a bellows, and the rubber sleeve and the bellows may be installed in a similar manner to the compression spring, which will not be repeated herein.

It should be noted that, referring to fig. 2, the limiting seat 200 and the first supporting portion 110 can clamp the battery module 400 under the action of the elastic member 310. In addition, the elastic member 310 also has a function of holding the protrusion 121 in the first limiting hole 221 or the second limiting hole 251.

It should be noted that, to facilitate connection of the lifting member 100 to the lifting power mechanism, the lifting hook further includes a first lifting ring 330. The lower end of the first hanging ring 330 is in threaded connection with the connecting sleeve 320. When the battery module 400 is lifted by the lifting hook, the power mechanism directly applies acting force to the battery module 400 through the first lifting ring 330 and the lifting piece 100.

Referring to fig. 8, in a modification of the above embodiment, the first stopper 220 includes a first stopper hole 221, and the second stopper 120 includes a protrusion 121. When the lifting member 100 is located at the first position, the first inner surface 222 of the first limiting hole 221 can abut against the protrusion 121 to limit the movement of the lifting member 100 along the first direction.

The first limiting hole 221 is matched with the protrusion 121, is in plug-in matching with the shaft, is simple in structure, and can limit the movement of the lifting piece 100 along the first direction with lower production cost when the lifting hook is produced, so that the production cost of the lifting hook is reduced.

In a modification of the above embodiment, referring to fig. 8, the first limiting portion 220 may also include a protrusion 121, and the second limiting portion 120 includes a first limiting hole 221, which is also beneficial to reducing the production cost of the hook.

Referring to fig. 9 and 10, in some embodiments of the present application, when the hanging member 100 is at the second position with respect to the battery module 400, the overlapping area of the projections of the first supporting portion 110 and the abutting portion 421 in the vertical direction is zero. Setting the direction opposite to the first direction as a second direction, wherein: the limiting seat 200 is further provided with a third limiting portion 250, and when the lifting member 100 is located at the second position, the third limiting portion 250 cooperates with the second limiting portion 120 to limit the movement of the lifting member 100 in the second direction (refer to fig. 10, for example, counterclockwise (viewing into the paper perpendicular to the paper)).

When the hoist 100 is separated from the battery module 400 in the upward direction, if the hoist 100 moves in the second direction, the first supporting part 110 may collide with the abutting part 421 (i.e., the battery module 400), resulting in damage to the first supporting part 110 and/or the battery module 400. For example, referring to fig. 10, when the hanging member 100 moves upward to be separated from the battery module 400, if the first supporting part 110 rotates counterclockwise (as viewed in the direction of the paper, inward), the first supporting part 110 may collide with the abutting part 421.

By restricting the movement of the hanging member 100 in the second direction, it is advantageous to reduce the risk of collision with the battery module 400 when the hanging member 100 is separated from the battery module 400.

In a further embodiment, referring to fig. 9 and 10 as appropriate, the lifting member 100 is further provided with a third limiting portion 250, the third limiting portion 250 cooperating with the first limiting portion 220 to limit movement of the lifting member 100 in the second direction when the lifting member 100 is in the second position. Similarly, by restricting the movement of the hanging member 100 in the second direction, it is advantageous to reduce the risk of collision with the battery module 400 when the hanging member 100 is separated from the battery module 400.

With reference to fig. 8, in a modification of the above embodiment, the second limiting portion 120 includes a protrusion 121, and the third limiting portion 250 includes a second limiting hole 251; when the lifting member 100 is located at the second position, the second inner surface 252 of the second limiting hole 251 can abut against the protrusion 121 to limit the movement of the lifting member 100 along the second direction.

Similarly, the second limiting hole 251 is matched with the protrusion 121, so that the hole is matched with the shaft in a plugging manner, the structure is simple, and the function of limiting the movement of the lifting piece 100 along the second direction can be realized at lower production cost when the lifting hook is produced, so that the production cost of the lifting hook is reduced.

Referring to fig. 8, in the modification of the above embodiment, in order to prevent the protrusion 121 from being separated from the stopper seat 200 during the process of moving the protrusion 121 from the first stopper hole 221 to the second stopper hole 251, the stopper seat 200 is further provided with a guide hole 230. One end (for example, the left end, see fig. 8) of the guide hole 230 communicates with the first limiting hole 221, and the other end (for example, the right end, see fig. 8) of the guide hole 230 communicates with the second limiting hole 251. Thus, when the protrusion 121 enters the guide hole 230, the third inner surface 231 of the guide hole 230 abuts against the protrusion 121, so that the protrusion 121 is guided, and the protrusion 121 can smoothly move from the first limiting hole 221 to the second limiting hole 251.

In addition, in the modification of the above embodiment, the first limiting hole 221 and the second limiting hole 251 may also penetrate through the limiting seat 200 downward, and after the protrusion 121 leaves the first limiting hole 221, the protrusion may also enter into the second limiting hole 251 through an external space.

Referring to fig. 11, a lifting device according to a second aspect of the present application includes a mounting frame 500 and the aforementioned hooks. The number of hooks is several, and one end of the hanging piece 100 of each hook far from the first supporting part 110 is connected with the mounting frame 500.
